Toponymy
The district is named after the hills of Khao Chakan, a group of limestone hills rising out of the valley alluvium. In the hills are several caves, including the cave temple Wat Tham Khao Chakan. The hills are habitat to about 2,000 crab-eating macaques.Its name literally translates as "relentless hill". Legendarily Hanuman shot an arrow through this hills, hence the name "Khao Thotsakan". Later, it became distorted to be Khao Chakan like today.
Another story is King Taksin brought his army through the area and performed a ceremony called "Cho-Kan" to terrorize the enemy. Later, people called distortions to Khao Chakan.
